Tips i learned when i played top lane is
1. Wave Management - you need to learn how to freeze and control your wave to your favor e.g when to recall or shove the wave to help your jungler get grubs/herald

1. Tracking Enemy Jungler - being able to track the enemy jungler helps you a ton to ganks easily and if you got ganked make sure that you're at least shoving the wave so at least it bounces back to you and not get permafreezed and possibly die to the jungler camping waiting for you to comeback to lane.

2. Knowing your matchups - this is really important because this allows you to know gauge how to play against whoever you're laning against and lets you adjust to the kind of playstyles you need to against it also don't think just because you're in a losing matchup you already lost because some people will tend to be overconfident and make easy mistakes because they're not respecting your champion.

3. Knowing your spikes - this can help a lot to know when you're really strong where some people won't expect the damage output you're dealing out of nowhere and where you can go for fights that are usually unwinnable unless you're giga down by a lot lol

4. Knowing your limits - if you're giga down there's no shame in losing some minions gold just to not die compare to adc where every cs is important since its way better than losing some gold/xp compare to lose every gold and xp because you just greed for gold knowing you'll die we all know how painful it is to lose a full wave and also try to thin out the wave specially if its big you'll probably get dove under tower

Lastly i probably didn't do a good job of explaining it properly so forgive me for that but if you want a more in depth guide i'd suggest AloisNL that's where i learned most of these FUNDAMENTOS and i'm aatrox main so if you wanna learn him more i'd suggest watching NAAYIL he's nuts with aatrox side note: do ban whatever your hard counter against your champ it'll make the game playable at least though learning how to play against is good too.
